Explanation:
The ideal gas equation is PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
Same Pressure and Temperature:
In this case, the pressure and temperature of the two flasks are the same. Therefore, we can write the equation as:
PV=nRT
Since the pressure, volume, and temperature are the same for both flasks, we can simplify the equation to:
n1R=n2R
where n1 is the number of moles of gas in flask A and n2 is the number of moles of gas in flask B.
Same Gas Constant:
Since the gas constant is the same for both flasks, we can further simplify the equation to:
n1=n2
Therefore, the two flasks contain the same number of moles of gas.
Same Number of Moles:
Since the number of moles of gas in the two flasks is the same, we can conclude that the two flasks contain the same number of molecules. This is because the number of molecules in a gas is directly proportional to the number of moles of gas.
Therefore, the correct answer is option B - The same number of molecules.
Two flasks A and B of 500 ml each are respectively filled with O2and S...
As the temperature and pressure conditions are identical, each flask will have same number of moles of gas as the other one, irrespective of which gas it contains, and since number of moles is equal so the number of molecules will also be equal.
